Naming diversity in an evolutionary context: Phylogenetic definitions of the clade (Campanulaceae/Campanuloideae) and the cryptic taxa within.

In recent times, evolution has become a central tenet of taxonomy, but nomenclature has consistently been decoupled from the tree-thinking process, often leading to significant issues in reconciling traditional (Linnaean) names with clades in the Tree of Life. Recent evolutionary studies on the clade, a group of endemic plants found in the Mediterranean Basin, motivated the establishment of phylogenetic concepts to formally anchor clade names on the Campanuloideae (Campanulaceae) tree. These concepts facilitate communication of clades that approximate traditionally defined groups, in addition to naming newly discovered cryptic diversity in a phylogenetic framework.
